The advantage is that you can visibly see the difference in the data. Disadvantage of line plots would be that not as appealing.
the answer is 4 because 16 and 20 can both be divided by 4.
Answer:
Its the 2nd one
Step-by-step explanation:
Simplify the exponents and then multiply
Remember that, for independent events, the probability that both occurr is the product of the individual probabilities.
a) Probability of being contacted: 78% = 0.78
Probaility of refusing: 1 - 22% = 1 -0.22 = 0.78
Combined probability: 0.78*0.78 = 0.6084
b) The probability of failing to contact or making contact and not geeting them to agree 1 - the probability of contacting and getting them to agree.
The probabilityof contacting and getting them to agree is 0.78*0.22 = 0.1716
The the answer to this question is 1 - 0.1716 = 0.8284
